5 Claims.

This invention relates to covers for containers and more particularly tocovers for bottles for milk, cream and various beverages, and itsprincipal object is to provide an improved cover for such containerswhich is composed of thick paper or like material and consists of acontainer mouth covering portion and a skirt portion depending therefromprovided with improved depending portions for securing it to the neck ofthe container.

Another object is to provide such depending portions in the form of tabsof different kinds. And a further object is to provide the dependingportions or tabs of the skirt portion with two ply or doubled partsthrough which fastener tongues can be passed for securing the tabs inposition when the container cover is in place on the container, said twoply portions being preferably formed by doubling under the end parts ofsuch depending portions or tabs.

These and various other features of our improved container covers nothereinbefore men:

tioned but which will hereinafter be disclosed, are illustrated in thedrawing accompanying and forming part of this specification, and inwhich- Figure 1 is a side elevation of a portion of a bottle and oneform of our improved container cover applied thereto.

Fig. 2 is a plan of the same.

Fig. 3 is a partial horizontal section enlarged taken on the line 33ofFig. 1.

Fig. 4 is a partial vertical section- Fig. 5 is a plan of a portion of astrip of blanks for the form of our invention shown in Figs. 1, 2 and 3,in process of manufacture.

Fig. 6 is a plan of the same showing the blanks ready for application tocontainers.

Fig. 7 is a transverse section of the completed blank taken on the line'I! of Fig. 6, and

Fig. 8 is a transverse section of the same taken on the line 8-8 of Fig.6.

Like characters refer to like of the drawing.

Referring first to Figs. 5, 6, 7 and 8 of the drawing, we have hereillustrated the blanks for the form of container cover shown in Figs. 1,2,

parts in all figures 3 and 4 and each of said blanks has a multisidedcentral or container mouth covering portion 3 formed by the scored lines4 and is ordinarily imperforate. The numeral 5 indicates the skirtportion of the'blank and of the container cover, and this part of theblank 2 is further scored at 6 and 6a and is perforated or slotted at 20forming two kinds of extending portions or tabs 9 and l0.

The extending portions or tabs 9 are preferably wider than the "tabs l0and are scored at 2| so that the end parts 22 can be folded under theadjacent or overlying parts 23 as shown in Figs. '1, 3, 4 and 7, thusforming a double thickness of the material at the points of applicationof the fasteners or staples. Ordinarily in this form of the invention,the material is thick paper which may become softened on contact withliquid and the fasteners hereinafter described may cut 10 through thepaper if only a single thickness of the same is provided on eachextending portion or tab 9. Preferably two thicknesses of material areprovided in the end portions of alternate tabs and this is done in thepresent form of the invention by doubling over the longer tabs thusforming a two ply end portion in the blank.

.Either of the end portions 9 and H] can be arranged in this way. Onapplying the blank to a container it will be seen that the tabs l0overlap 20 the tabs 9 for reinforcing the skirt portion and the tabs IDare arranged uppermost or outwardly when they are in position on thecontainer neck and the parts of the undermost tabs which may retainmoisture are given additional strength 25 furnished by the doubling ofthe material at 22 and 23.

This form of the invention has short plaits l6 formed along the scorings6 and 6a, but said plaits preferably do not extend more than halfway 30down the 'skirt portion when the cover is applied to a container. Bymeans of this construction the container cover is more readily adjustedto the small variations in the sizes of containers such as bottles, andwhich are inherent in the manu- 35 facture of such containers as bottlesand the like of glass and material of similarv nature. Thus the skirtportion still retains the advantages of a non-perforated and plaitedupper part. Each container cover is provided with a pulling 40 tab 25herein shown at the lower left hand of each blank in Figs. 1, 5 and 6.Ordinarily it'projects down below the lower edge 26 of the'skirt portion5 when the cover is in place on the container as illustrated in Fig. l.

The method of applying the blanks in this form of the container consistsin centering the blanks by suitable means, (not shown) then placing iton the container mouth M, then pushing down the skirt portion 5 with itsdepending portions or tabs 9 and Ill until it reach the position shownin Fig.

1. It will be noted that the wider tabs 9 underly the tabs I 0 at theside edge parts of the respective tabs. Any suitable means may beemployed to hold the tabs in position and the means prefer- 66 ably usedare in the form of metallic fasteners such as the staples l8 which arethen pushed through the overlapped side edge parts of the said tabs 9and Ill, thus securing the skirt portion firmly on the container neck n.

The method of forming the material for this form of our invention isillustrated in Figs. 5 to 8 inclusive and consists in first scoring thecentral or container mouth covering portions 3 in a strip of materiall2, forming skirt portions 5 by suitable scorings 6 and 6a andperforating at 20 so as to form a plurality of extending portions ortabs 9 and I0 projecting or radiating from the central portions, thenscoring or weakening parts, preferably adjoining or on connecting tabsbetween adjacent blanks to form severing portions as at l3, and thenfolding the end portions I2 of alternate tabs on the lines I so as toform two ply end parts. In some instances we may apply adhesive ofsuitable kind to the contacting surfaces of the two ply doubled underparts. Thus we have a more durable, and adjustable container cover andone adapted to be applied to the containers by machine.

It is apparent that changes and modifications can be made in ourinvention which will be within the scope and spirit thereof, and we donot therefore confine ourselves to the exact details of constructionshown and described herein, and furthermore we do not confine ourselvesto the precise details and order thereof in the method of forming thematerial for making container covers and the like except as defined bythe appended claims.

What we claim is:

1. A container cover comprising a container mouth covering portion, askirt portion depending therefrom having flaps ending in interlappedtabs, alternate tabs being primarily the longer and brought to equallength with the intermediate tabs by the folding of their end parts forassisting in holding thecover on the container, and fastening membershaving portions lying on and spanning the outer middle parts of saidintermediate tabs and portions passed through the adjacent interlappedtabs.

2. A container cover comprising a multi-sided container mouth coveringportion, a skirt portion depending therefrom having flaps extending fromthe side edges of the first mentioned portion and ending in tabs definedby outwardly extending ,end parts of the intermediate tabs and havingparts passed through the interlapped tab parts whereby the tabs areclamped together.

3. A container cover comprising a container mouth covering portion, askirt portion depending therefrom having a plurality of flaps ending intabs interlapped at their side edge parts, said tabs defined byoutwardly extending rectilinear slots in the skirt portion, alternatetabs having integral inwardly folded end parts whose side edges underliethose of the intermediate tabs, and a plurality of fastening memberseach spanning the middle of the end part of an intermediate tab andpassed through the side edge parts of the adjacent tabs and whereby thesame and the intermediate tabs are clamped together.

4. A container cover comprising a container mouth covering portion, askirt portion depending therefrom having a plurality of depending tabsinterlapped at their side edges, said tabs defined by rectilinear slotsin the outer part of the skirt portion, alternate tabs having inwardlyfolded end parts, the lower side edge parts of said tabs underlyingthose of the intermediate tabs, and a plurality of wire staples havinglongitudinal parts lying directly against the middle portions of the endparts of said intermediate tabs and prong ALBERT F.
